GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disk, CD-ROM, etc.) to another, trying to rescue the good parts first in case of read errors. GNU ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile contents, converts logfiles to/from other formats, compares logfiles, tests rescue status, and can delete a logfile if the rescue is done.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving. Lzip is a clean implementation of the LZMA algorithm. The Lzip file format is designed for long-term data archiving. It is clean, provides very safe four factor integrity checking, and is backed by the recovery capabilities of lziprecover.

Lziprecover is a data recovery tool and decompressor for files in the lzip compressed data format (.lz) able to repair slightly damaged files, recover badly damaged files from two or more copies, extract data from damaged files, decompress files, and test integrity of files. Lziprecover is able to recover or decompress files produced by any of the compressors in the lzip family; lzip, plzip, minilzip/lzlib, clzip, and pdlzip. It makes lzip files resistant to bit-flip, one of the most common forms of data corruption, and its recovery capabilities contribute to make of the lzip format one of the best options for long-term data archiving.

barvinok is a library for counting the number of
integer points in parametric and non-parametric
polytopes based on polylib. For a parametric
polytope, the number of points is represented by
either a piecewise quasi-polynomial or an Ehrhart
series.

GNU ed is an 8-bit clean implementation of the POSIX line-oriented text editor. Ed is the "standard" text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.

Listaller unifies the way you manage software on your Linux system by providing a user-friendly, application-centered software manager GUI. It also provides a software setup package format (the IPK package format), which works on all Linux distributions, as well as tools to make your application binaries work on every Linux distribution. The project has merged with Autopackage some time ago. One of Listaller's strengths is its close integration with AppStream and PackageKit. This means that you will be able to manage Listaller-installed applications with your favorite package-manager, like GNOME-PackageKit, Apper, or even the Ubuntu Software Center. Listaller is primarily designed to be run on Linux distributions, but it could be ported to *BSD.

DV Analyzer is a technical quality control and reporting tool that examines DV streams in order to report errors in the tape-to-file transfer process, such as video error concealment information, invalid audio samples, timecode inconsistency, inconsistent use of arbitrary bits in video DIF blocks, and DIF structural problems. DV Analyzer also reports on patterns within DV streams such as changes in DV time code, changes in recording date and time markers, first and last frame markers within individual recordings, and more.

evol (entrenched virtues of Lisp (love reversed)) aims to be a compatible and full-fledged replacement for the GNU autotools stack. It is targeted at coping with the autotools' shortcomings while not repeating the mistakes made by comparable build tool projects.
